Quran 34:52 · Saba

When an individual rejects the Truth in the present world, the result of doing so is not immediately apparent. This position emboldens him to reject the Truth; he does not consider the call for Truth worth giving serious attention to. He describes it with contempt and rejects it carelessly. But the day when the system of the present world collapses, the whole picture will change. He will come to know that this reality which he had ignored was the most important of all. The bubble of vanity will be pricked and he will start spontaneously appreciating and admitting the Truth, which he had considered unworthy of attention in the pre-death period. But, by then, the moment for this would have passed, and he will be told that acceptance at a time when realities were as yet invisible would have had value, whereas acceptance at a time when the truth is plainly visible has no value. This is the picture of the psychological condition of those who deny the truth. The Truth which was presented to them in this world was so powerful that they found themselves unable to reject it on the basis of reasoning. But, as this Truth fitted ill with their mental mould, they were not ready to accept it either. This ambivalent condition had pushed them into and kept them in a peculiar state of inner conflict, till the angel of death arrived and lifted the veil from their eyes, which they themselves should have removed but did not.
